The heating cooker configured as described above can select cooking from a plurality of types of cooking menus. Cooking menus include cooking menus using eggs. An example of making an open omelet as an example of a cooking menu using eggs using the heating cooker configured as described above will be described below.

<How to make an open omelet (cooking method)>
FIG. 6 is a table showing stirring conditions of the stirring unit 11 when making an open omelet. Here, the stirring conditions in two steps (first stirring period (1), second stirring period (2)) performed before the baking process when making an open omelet are shown. That is, in the heating cooker, when an open omelet is selected from a plurality of cooking menus by the display operation panel 5, two stirring steps (first step , second step) are performed, and then the baking process (third step) is performed.

The first stirring period (1) is a loosening period for loosening the eggs put in the inner pot 10 . In the first stirring period (1), the stirring period is set to 1 minute, the ON time is set to 1/5, and the stirring unit 11 is intermittently rotated less than one rotation. Here, the number of revolutions of the stirring unit 11 in the first stirring period (1) (indicated by *1 in FIG. 6) indicates a number of revolutions less than one. Therefore, in the first stirring period (1), the ON time is 1/5, so during the 1 minute stirring period, the stirring unit 11 is rotated forward for less than 1 rotation for 1 second out of 5 seconds, and for the remaining 4 seconds. 12 times, the stirring unit 11 is reversely rotated and stopped. Specifically, in the first stirring period (1), in a 1-minute stirring period, the stirring unit 11 is rotated less than 1 rotation (for example, 120°) forward for 1 second out of 5 seconds, and in the remaining 4 seconds 12 times. The rotation angle of forward rotation less than one rotation is not limited to 120°, and the rotation angle of reverse rotation is not limited to 30°.

The second stirring period (2) is the main stirring period in which the egg is loosened in the inner pot 10 in the first stirring period (1) and mixed with other ingredients, and then fully stirred. is. In the second stirring period (2), the rotation speed of the stirring unit 11 is set to 100 rpm, the ON time is set to 2/4 (the stirring unit 11 is driven for 2 seconds out of 4 seconds), and the stirring period is set to 30 seconds. . Therefore, in the second stirring period (2), since the ON time is 2/4, the rotation of the stirring unit 11 at 100 rpm is performed for 2 seconds out of 4 seconds, and the remaining 2 seconds are stopped for 30 seconds. continue. That is, in the second stirring period (2), within the stirring period of 30 seconds, the stirring unit 11 is rotated for 2 seconds out of 4 seconds, and the stirring unit 11 is stopped for the remaining 2 seconds, which is repeated 7.5 times.

The stirring conditions shown in FIG. 6 show an example, and are not limited to each numerical value. That is, the number of rotations of the stirring unit 11 in the first stirring period (1) is not limited to less than 1 rotation, and may be 1 rotation (360°) as long as the egg can be put in and loosened. It may be less than 2 rotations (eg 480°) or less than 3 rotations (eg 840°). Alternatively, the number of revolutions may be three or more, but preferably less than the number of revolutions of the stirring unit 11 during the second stirring period (2). If the rotation speed is increased, the egg and the ingredients are mixed strongly, so there is a risk of the ingredients scattering, while if the rotation speed is decreased, the egg and ingredients are loosely mixed. Therefore, ingredients may not be mixed evenly. From this, the rotation speed of the stirring unit 11 in the first stirring period (1) depends on the size of the inner pot 10, the size of the stirring unit 11, the amount of eggs put into the inner pot 10, and the amount of ingredients. can be set as appropriate. In addition, the rotation speed of the stirring unit 11 in the second stirring period (1) is not limited to 100 rpm, and may be less than 100 rpm as long as the beaten eggs and ingredients can be uniformly mixed. , may be greater than 100 rpm.

Further, in the first stirring period (1), intermittent rotation of the stirring unit 11 includes forward rotation and reverse rotation in order to loosen the egg and mix it with the ingredients. However, the intermittent rotation of the stirring unit 11 may be only forward rotation. That is, in the first stirring period (1), the stirring unit 11 is rotated less than 1 rotation (for example, 120°) forward in a stirring period of 1 minute, then the rotation is stopped, and the stirring unit 11 is rotated less than 1 rotation again. It may be repeated to stop the rotation after forward rotation (for example, 120°).

Further, in the second stirring period (2), the stirring unit 11 is continuously rotated at 100 rpm for 2 seconds of the ON time for 30 seconds, and the rotation of the stirring unit 11 is stopped for the remaining 2 seconds. Thus, in the second stirring period (2), the stirring unit 11 intermittently rotates. By intermittently rotating the stirring unit 11 in this way, it is possible to introduce air into the beaten egg, which is the object to be stirred, and to make the final open omelet fluffy.

In the stirring conditions shown in FIG. 6, the second stirring period (2) is set shorter than the first stirring period (1). This is because during the first stirring period (1), it is preferable to intermittently rotate the stirring unit 11 for a certain period of time in order to loosen the eggs and mix the ingredients uniformly. On the other hand, in the second stirring period (2), since the egg and the ingredients are already uniform in the first stirring period (1), the stirring unit 11 can be rotated as fast as possible in a short time. This is because it is preferable.

Here, as described above, within the first stirring period (1), there are an ON time (first drive time) during which the stirring unit 11 is driven and an OFF time (first non-driving time) during which the stirring unit 11 is not driven. set alternately. Also, within the second stirring period (2), an ON time (second driving time) during which the stirring unit 11 is driven and an OFF time (second non-driving time) during which the stirring unit 11 is not driven are alternately set. there is As in the stirring conditions shown in FIG. 6, the ON time of the second stirring period (2) is preferably longer than the ON time of the first stirring period (1).

The eggs and the ingredients stirred in the inner pot 10 under the stirring conditions shown in FIG. Here, the heating control unit 100a of the control device 100 turns the heating circuit (heating unit) 40 so that the inner pot 10 is heated for a predetermined time according to the selected cooking menu after the second stirring period (2) ends. An open omelet is finished in the inner pot 10 by being controlled.

7 to 9 show the state inside the inner pot 10 during the cooking process of the first stirring period (1), the cooking process of the second stirring period (2), and the heating process. FIG. 7 is a schematic cross-sectional view illustrating the state inside the inner pot 10 during the first stirring period (1). FIG. 8 is a schematic cross-sectional view illustrating the state inside the inner pot 10 during the second stirring period (2). FIG. 9 is a schematic cross-sectional view illustrating the state inside the inner pot 10 during the heating process.

In the first stirring period (1), as shown in FIG. 7, three eggs 90, ingredients (such as bacon) 91 cut into predetermined sizes, and seasonings are put into the inner pot 10. The first stirring arm 13A and the second stirring arm 13B of the stirring unit 11 are placed in a stirring state (inverted state), and the stirring unit 11 is intermittently rotated. During the first stirring period (1), the step of mixing the egg 90 with the ingredients 91 while loosening it in the inner pot 10 is performed. The number of eggs 90 put into the inner pot 10, the type, size and amount of ingredients 91, and the type and amount of seasoning are not particularly limited, and may be appropriately adjusted according to the content of cooking.

In the second stirring period (2), the eggs 90 and ingredients 91 mixed in the inner pot 10 are stirred in the stirring unit 11 in a state where the stirring in the first stirring period (1) is completed. A further mixing step is performed by the first stirring arm 13A and the second stirring arm 13B of the stirring unit 11 . Thereby, as shown in FIG. 8, the egg 90 and ingredients 91 can be uniformly mixed in the inner pot 10 .

In the third stirring period (3), after the stirring in the second stirring period (2) is completed, the first stirring arm 13A and the second stirring arm 13B are placed in a non-stirring state (inverted state) as shown in FIG. ), the inner pot 10 is heated by the heater 41 for a predetermined time, and the open omelet 92 is finished. That is, by heating the inner pot 10 in which the eggs 90 and ingredients 91 are uniformly mixed for a predetermined time, an open omelet 92 is baked in the inner pot 10 as shown in FIG.

As described above, in the heating cooker of the present embodiment, when making the open omelet 92, the eggs 90, the ingredients 91, and the seasoning, which are the ingredients, are put into the inner pot 10, the lid 2 is closed, and the display operation panel is displayed. By selecting open omelet cooking from 5, an open omelet 92 is automatically subjected to processes from loosening eggs to baking. When the cooking is finished, the lid body 2 is opened and the completed open omelet 92 is taken out. In this way, the open omelet is made from the time the lid 2 is closed until the lid 2 is opened, so the user does not have to do anything while the open omelet 92 is being cooked. For example, it is not necessary to break the egg, loosen it, and mix the ingredients. Therefore, the user's burden during cooking of the open omelet 92 can be reduced.

In the heating cooker according to the present embodiment, open omelet cooking has been described as an example, but any cooking menu that uses eggs and requires the eggs to be loosened can be used for cooking. is possible. Further, in the first stirring period (1), the object to be loosened may be minced meat instead of eggs. Therefore, a cooking menu using minced meat can also be cooked by the heating cooker described in this embodiment. As described above, if the cooking menu includes a cooking process that requires loosening any ingredients, the heating cooker according to the present embodiment can be preferably used.
